hot... someone you find that just makes you melt when he comes on the screen. Take for example Oguri Shun in Hana Yori Dango. there are certain parts when he can just look into the camera and you will just melt. It's that power that makes people hot. The more you can control it, the hotter you are. Sometimes you don't even have to be physcially attractive to be hot. hahah take Paris Hilton for example.
